Abstract

Aim of the study. 1. Evaluating the activity of temporomandibular joints manifesting features of dysfunction in students of the Medical University Gdańsk, 2. Quantitative analysis of the disorders occurring in temporomandibular joints. 3. Proving the correlation between the investigated parameters and the analysed dysfunctions in temporomandibular joints
The materials and research method. For the examination, 40 students in the age of 19 to 27 years (21 women and 19 men) were classified, representing the average age of 23 years.  For the needs of this study, a card of patient examination had been constructed. The evaluation covered, among others, such parameters as: the mobility range of the jaw, the Rozencwaig’s dyskinesia index, the movement of the joint head during the jaw abduction, acoustic symptom, pain index, the presence of trigger points, the cervical spine mobility range.  The obtained results were subjected to statistical analysis with the application of Statistica 10 software .
Results. Analysis of the investigated parameters revealed that dysfunctions of mobility range, at least in one direction, occur in 87,5% (n=35) of the examined persons. The Rozencwaig’s dyskinesia index was proven in 37,5% (n=15). Asymmetric movement of the joints heads occurred in 67,5% (n=27) of the examined persons; and the disorders of the jaw guiding track and the presence of the acoustic symptom were revealed in 80% (n=32) out of the total 40 of the examined persons. Among 57,5% (n=23) of the examined, the presence of trigger points was revealed within the masseter and the temporalis muscles, or in one of them. Dysfunction of the temporomandibular joints correlates, among others, with a reduction of the mobility range in the cervical spine, with acoustic symptoms and presence of parafunctions.
Conclusions. A significant percentage of the temporomandibular joints dysfunctions was observed among students. Attention was attracted by the high percentage of people performing parafunctions. Correlations statistically significant for the temporomandibular joints were proven.
